• If the system did not come racked, the SSR would rack the necessary components before the
installation starts.
• IBM Elastic Storage System 3200 needs to be placed in the rack location provided by the user. For
example, EIA 1-2 and 3-4.
– Each additional IBM Elastic Storage System 3200 unit needs 2U space in the rack.
• The EMS node needs to be racked into the frame.
– One EMS node is required per IBM Elastic Storage System 3200 cluster.
• Management switch
IBM Elastic Storage System 3200 is a unique system as it has a single management port that serves
both deployment (operating system level) and service (BMC/BIOS/Power control) functions. This is a
shared port with two MAC addresses (one for each function).
– A 1 Gb switch is required.
– There must be a dedicated switch/subnet for ESS or shared switch with isolated VLANs for ESS.
– It is recommended to procure this switch from IBM, but customer-provided switch can also be used.
If the management switch was purchased from IBM and was racked along with the ESS system,
setup for VLAN has been done correctly and no further configuration would be required. However,
if it did not come racked, the switch would require to be setup with the correct VLAN configuration.
For more information about instructions on switch VLAN configuration, see Appendix B, "Switch VLAN
configuration instructions," on page 107 and Appendix C, "Dual 24 port (48 ports) MGMT switch ESS
configuration," on page 115.
If the switch was not purchased from IBM, there must be two isolated VLANS for ESS management.
Do note that the customer provided switch might not be supported by IBM.
Note: ESS 3200 requires certain ports to be "trunk" ports. On an IBM-sold switch there are ports
1-12. These ports, when combined with the vlag tag set at the BMC, would route VLAN101 traffic to
the BMC vlan. If the switch is a customer-provided, they would need to create these trunk ports and
make sure that the proper VLAN tag is set on each canister BMC port.
– The switch must be placed in the rack, cabled, powered on, and properly VLAN'd for the SSR to start.
• High-speed switch
– 100 Gb Ethernet or 200 Gb InfiniBand is supported (from IBM or customer provided).
– This switch is not required to be in place for the SSR to start but it must be ready before the customer
begins the cluster setup.
– The SSR is not responsible for this switch. If the switch is already racked and cabled, the SSR might
plug-in to the adapters.
– A 40 Gb Ethernet switch can be used with the proper connectors.
Supported connectors per network type:
– EDR cables: QSFP28
– 100 Gb cables: QFSP28 (but different from the EDR cables)
– 40 Gb cables: QSFP+
Note: It is recommended to use IBM branded connectors, especially for the adapter side. When using
your own switch, ensure that the connectors are compatible with the switch.
• Ethernet cables (3) run from the 1 Gb or 10 Gb management switch to the POWER9 EMS.
POWER9 EMS node:
– Slot C11, Port T1 - EMS management / xCAT network
– Slot C11, Port T2 - FSP / Service VLAN connection
– HMC1 port (FSP VLAN connection)
